Thinking of selling... where do I start?

[MnDancer]

I've finally convinced my daughter to let go of some of the toys she never plays with anymore. I promised her I would sell her LPS toys and she can keep the money. All of hers are from 2002 or newer. Are there any from that time frame that are worth more than others that I should look out for? She has a huge collection, so it wouldn't be practical to do a price check on all of them. But if there are some HTF ones that I should be paying attention to, it would help to know. Sometime this weekend I'll take a pic of them all, but any selling advice until then would be helpful!
